How do plants help give energy to animals?
What is plants make sugar with sunlight; animals eat plants for energy?
The Moon's gravitational pull on Earth causes the ocean waters to rise and fall in a predictable pattern twice per day. This phenomenon is called this.
What are tides?
Describe one piece of evidence (other than fossil distribution) scientists use to support past plate motions.
What is matching coastlines or magnetic striping / seafloor pattern?
In a collision between two objects, how is momentum conserved?
What is total momentum before = total momentum after; vector sum conserved if no external forces?
Give one simple example of stored energy changing to motion.

What is cells break down sugar to release energy (ATP)?
Give one simple piece of proof that Earth changed long ago.
What is rock layers or fossils show past seas or movements.
Explain how the cycling of water between atmosphere, oceans, and land is driven by the Sun and gravity (give two steps in the cycle).
What is evaporation and precipitation (or evaporation → condensation).
In a hit between two objects, what stays the same if no outside push acts?
What is Momentum.
If frequency goes up, what happens to the wavelength?
What is the Wavelength goes down. (decreases)
Which group of cells combines to form the tissue that contracts to move your arm?
What is muscle cells form muscle tissue move the body?
The Sun's core reaches temperatures of about 27 million degrees Fahrenheit, where hydrogen atoms fuse together to form helium and release enormous amounts of energy.
